1. A lancing device comprising:
- a housing having an open tip end;
an operation mechanism for advancing a lancet from inside the housing toward the tip end of the housing; and
a lancing adjustment mechanism including an operation member which is operated for adjusting a lancing depth of the lancet into a target portion upon forward movement of the lancet;
wherein the lancing adjustment mechanism provides a nonlinear relationship between the lancing depth of the lancet and an operation amount of the operation member.

Abstract
A lancing device (A) includes a lancing adjustment mechanism for adjusting the lancing depth of a lancet (L) into a target portion (99) by operating an operation member (20c). The lancing adjustment mechanism is designed to provide a nonlinear relationship between the lancing depth of the lancet (L) into the target portion (99) and the operation amount of the operation member (20c). With this arrangement, it is possible to suitably adjust bleeding at the lanced portion, thereby improving the operationality of the lancing device (A).
